肠易激综合征的胆囊收缩功能

本文对１５例肠易激综合征（ＩＢＳ）和１０例健康对照的胆囊收缩功能进行了研究。应用超声显像测定了以下参数：（１）空腹胆囊容积（ＦＧＶ），（２）服脂餐后胆囊达最大收缩时残余容积（ＲＧＶ），（３）胆囊最大排空率（ＭＧＥＲ），（４）达最大收缩的经历时间。结果显示，ＩＢＳ患者的ＦＧＶ、达最大收缩时ＲＧＶ及经历时间均显著大于对照组（均为Ｐ＜０．０１），而其ＭＧＥＲ则显著小于对照组（Ｐ＜０．０１）．提示ＩＢＳ患者的胆囊收缩功能显著异常。     

肝硬化患者血浆VIP、CCK水平与胆囊排空功能的关系

探讨肝硬化时血浆胃肠激素水平对胆囊运动的影响。用放免法测定肝硬化患者及对照者血浆血管活性肠肽 (VIP)和胆囊收缩素 (CCK)含量 ;用B超测定餐前、餐后胆囊容积及排空率。结果 :肝硬化时血浆VIP、CCK均明显增高 (P <0 0 1,P <0 0 5 ) ;胆囊空腹容积、剩余容积均明显增大 (P <0 0 1,P <0 0 0 1) ,最大排空率较对照组无明显差异 (P >0 0 5 ) ,但Child -PughC级降低 (P <0 0 5 )。肝硬化组胆囊最大排空率与VIP呈负相关 ,胆囊空腹容积及剩余容积与VIP均呈正相关 ,胆囊空腹容积、剩余容积及最大排空率与CCK均无相关。提示肝硬化时VIP增高既抑制胆囊运动 ,又明显降低胆囊张力 ,肝硬化时可能存在对CCK的抵抗。

Gallbladder emptying in patients with primary sclerosing cholangitis

AIM： To assess gallbladder emptying and its association with cholecystitis and abdominal pain in patients with primary sclerosing cholangitis （PSC）. METHODS： Twenty patients with PSC and ten healthy subjects were investigated. Gallbladder fasting volume, ejection fraction and residual volume after ingestion of a test meal were compared in patients with PSC and healthy controls using magnetic resonance imaging. Symptoms, thickness and contrast enhancement of the gallbladder wall and the presence of cystic duct strictures were also assessed. RESULTS： Median fasting gallbladder volume in patients with PSC [67 （19-348） mL] was twice that in healthy controls [32 （16-55） mL] （P 〈 0.05）. The median postprandial gallbladder volume in patients with PSC was significantly larger than that in healthy controls （P 〈 0.05）. There was no difference in ejection fraction, gallbladder emptying volume or mean thickness of the gallbladder wall between PSC patients and controls. Contrast enhancement of the gallbladder wall in PSC patients was higher than that in controls; （69% ± 32%） and （42% ± 21%） （P 〈 0.05）. No significant association was found between the gallbladder volumes and occurrence of abdominal pain in patients and controls.CONCLUSION： Patients with PSC have increased fasting gallbladder volume. Gallbladder Mucosal dysfunction secondary to chronic cholecystitis, may be a possible mechanism for increased gallbladder.     

Gall Bladder Emptying in Patients with Corrosive-Induced Esophageal Strictures

Ingestion of corrosive substances can lead to strictures of the esophagus and stomach. Cicatrization of the lower part of the esophagus can entrap vagal fibers in the process of fibrosis. The aim of the present study was to evaluate gallbladder dysfunction as a sequel to vagal damage in patients with corrosive-induced esophageal strictures. The cephalic phase of gallbladder emptying was stimulated by modified sham feeding according to the chew-and-spit method. Gallbladder volume was measured by ultrasonography using the ellipsoid method after an overnight fast and every 15 min for a period of 90 min after sham feeding in 22 patients and 10 controls. Mean fasting gallbladder volume was significantly greater in patients than in controls (22.09± 9.78 vs. 14.61± 4.42 ml; P = 0.025). After sham feeding the gallbladder ejection fraction was significantly lower in patients than in controls (32.86± 17.21 vs. 49.40± 7.86%; P = 0.007). Patients with cicatrization in the distal one-third of the esophagus had a greater basal gallbladder volume (24.57± 9.2 ml) and significantly lower ejection fraction (20.47± 8.9%) than patients with strictures at other sites (gallbladder volume, 18.50± 10.69 ml; ejection fraction, 47.48± 13.3%; P = 0.001). In conclusion, patients with corrosive-induced esophageal strictures, especially those in the distal one-third, had an increased fasting gallbladder volume and decreased cephalic phase of gallbladder emptying, pointing to impaired vagal cholinergic transmission, possibly due to vagal entrapment in the cicatrization process.

The effect of acute oral erythromycin on gallbladder motility and on upper gastrointestinal symptoms in gastrectomized patients with and without gallstones: a randomized, placebo-controlled ultrasonographic study

OBJECTIVE: Gastrectomy might be a risk factor for cholelithiasis and gallbladder stasis might play a major role. We studied fasting and postprandial gallbladder motility with 600 mg oral erythromycin or placebo in gastrectomized patients (with and without gallstones) and controls. METHODS: Seventeen patients operated on for gastric cancer (subtotal gastrectomy: n = 10, total gastrectomy: n = 7) were compared with 20 sex- and body-size matched healthy controls. Subjects randomly received erythromycin or placebo 30 min before the ingestion of a standard 200 ml liquid test meal. Gallbladder volume was estimated by ultrasonography until 120 min after test meal. A visual analog scale monitored GI perception of appetite, satiety, nausea, abdominal fullness and epigastric pain. RESULTS: Gastrectomized patients had increased fasting gallbladder volume (35.9 +/- 3.4 ml versus 21.0 +/- 1.4 ml, p = 0.0005) with faster postmeal emptying (T/2 14.8 +/- 1.1 min versus 23.5 +/- 1.5 min, p = 0.00019) than controls. Six patients developed small and asymptomatic gallstones, which did not influence gallbladder motility. In these patients, fasting gallbladder volume increased with time after surgery (r = +0.82, p = 0.047). Perception of satiety, abdominal fullness, and epigastric pain after ingestion of the test meal were all significantly greater in patients than in controls. Erythromycin significantly enhanced gallbladder emptying during fasting (p = 0.001) and postprandially in both patients and controls (0.002 < p < 0.017) and significantly reduced postmeal satiety and epigastric discomfort in gastrectomized patients. CONCLUSIONS: Increased fasting volume might be a form of stasis, predisposing patients to gallstone formation. Erythromycin improves fasting and postprandial gallbladder emptying and decreases upper GI symptoms in gastrectomized patients.     

50例非心源性猝死患者心肺复苏后24小时内左室功能变化的临床研究

目的：研究心肺复苏后多器官功能障碍综合征（PR-MODS）患者在24h内左心室功能变化规律。方法：对急诊50例既往无心功能障碍的PRMODS患者，监测心肺复苏后12、24h左心室舒张末期容积（LVEDV）、收缩末期容积（LVESV）、射血分数（LVEF）和每搏输出量（SV）。将存活〉12h组与存活〈12h组比较。结果：存活〉12h组（36例）其LVEDV和LVESV高于正常值[（106．22±16．06）ml vs （70．0±20．0）ml，t=16．96，P〈0．01；（46．94±11．72）ml vs （24．0±10．0）ml，t=11．74，P〈0．01）]；且其12h内LVEDV和LVESV低于存活〈12h组（14例）[（112．58±16．06）ml vs（129．35±21．15）ml，t=3．03，P〈0．01；（51．56±14．12）ml vs （64．14±14．32）ml，t=2．82，P％0．01）]。存活〉12h组其LVEF和SV低于正常值[（48．78％±5．76％）vs 〉50％；（62．17±5．56）ml vs（71．3±9．97）ml ，t=7．74，P〈0．01）]；且12h内LVEF和SV高于存活〈12h组[（45．06％±6．62％）vs （39．43％±8．14％），t=2．53，P〈0．01；（56．31±7．10）ml vs（54．57±6．80）ml，t=0．78，P〈0．01）]。结论：PR-MODS患者左心功能均较正常低下，且存活时间与心脏损伤程度有关。     

Gallbladder Contractility in Liver Cirrhosis: Comparative Study in Patients with and Without Gallbladder Stones

An increased prevalence of gallstones was demonstrated in patients with liver cirhosis, higher in the advanced stages of the disease. Some studies have found impaired emptying of the gallbladder in cirrhotic patients. Our aim here was to investigate gallbladder emptying in cirrhotic patients with and without gallstones to find out whether emptying is further impaired in the presence of gallstones. The study group comprised 24 patients with liver cirrhosis and gallstones, 8 in each Child class. The controls were represented by 18 cirrhotic patients without gallstones, 6 in each Child class. Fasting gallbladder volume was calculated by ultrasound using the ellipsoid formula. Gallbladder emptying was evaluated for 90 min after ingestion of a solid-liquid meal (14 g fat, 425 kcal), by assessing minimal residual volume, gallbladder ejection fraction, and area under emptying curve at 15-min intervals. Statistical analysis was performed using the two-tailed Students' t test and Pearson's correlation coefficient. In controls, gallbladder fasting and residual volumes increased with the severity of cirrhosis, but gallbladder emptying did not change significantly. In cirrhotics with gallstones, gallbladder emptying decreased in Child C compared with Child A class patients and, also, compared to Child C controls. The number or size of gallstones, as well as the thickness of the gallbladder wall, did not correlate with gallbladder emptying parameters. Gallbladder contractility is impaired in patients with liver cirrhosis and gallstones. Hypomotility is proportional to the severity of liver disease. Gallbladder hypomotility might contribute to the increased gallstone formation in patients with advanced cirrhosis.     

己酮可可碱对小鼠酒精性肝病酒精代谢酶和核受体PPAR-α的影响

目的：研究己酮可可碱（PTX）对酒精性肝病小鼠酒精代谢酶和过氧化物酶增殖物激活受体（PPAR-α）的影响。方法将64只 C57BL/6小鼠随机分为模型组、治疗组和对照组,用50%酒精灌胃建立急性肝损伤模型,以20%酒精连续灌胃6周建立慢性酒精性肝病模型;采用比色法检测各组小鼠血清乙醇脱氢酶（ADH）和细胞色素 P4502E1（CYP2E1）活性;采用 RT-PCR 法检测肝组织 ADH、CYP2E1和 PPAR-α mRNA 水平;采用免疫组化法检测肝组织 CYP2E1和 PPAR-α蛋白表达。结果急性和慢性酒精性肝损伤模型小鼠血清 ADH 活性分别为（11.2±1.6）U/ml 和（5.8±1.4）U/ml,与相应对照组比无显著性差异[分别为（12.5±1.2）U/ml 和（4.3±0.6）U/ml];急性和慢性酒精性肝损伤小鼠 CYP2E1活性分别为（12.2±1.8）U/ml 和（11.8±1.7）U/ml,均显著高于对照组[（7.9±1.4）U/ml 和（6.5±1.2）U/ml,P〈0.01）]和治疗组[（8.1±1.5）U/ml 和（7.8±1.5）U/ml,P〈0.01];急性和慢性酒精性肝损伤小鼠肝组织 CYP2E1阳性细胞相对表达强度为（765±21）和（682±25）,均显著高于对照组[分别为（308±12）和（305±18）,P〈0.01）]和大剂量 PTX 治疗组[分别为（521±18）和（418±12）,P〈0.01];急性和慢性酒精性肝损伤小鼠肝组织 ADH mRNA 水平与对照组比无显著性差异,但肝组织 CYP2E1 mRNA 相对水平分别为（1.47±0.32）和（1.13±0.52）,显著高于对照组[（0.89±0.23）和（0.45±0.28）,P〈0.01）]及大剂量 PTX 治疗组[分别为（0.92±0.27）和（0.48±0.32）,P〈0.01）];急性酒精性肝病动物肝组织 PPAR-α mRNA 水平与对照组或 PTX 治疗组比无统计学差异,但慢性酒精性肝损伤小鼠肝组织 PPAR-α mRNA 相对水平[（0.45±0.31）]显著低于对照组[（0.85±0.21）,（P〈0.05）];急性和慢性酒精性肝损伤小鼠肝组织 PPAR-α阳性相对表达强度为（322±15）和（262±23）,均显著低于对照组[分别为（721±18）和（689±14）,（P〈0.01）]和大剂量 PTX 治疗组[分别为（548±20）和（725±19）,P〈0.01）]。结论 PTX 能够减轻急慢性酒精性肝损伤,可能与其上调酒精代谢酶 CYP2E1和下调 PPAR-α表达有关,而与ADH 无关。
